Question

4. If Robert has $45 and has decided to double that amount every month, how much money will he have after 16 months? Robert’s earnings can be described by the function y = 45 * 2x. (Put that function into your calculator, graph and go to table and find when x = 16 months).

Answer 7

There are two questions. You cannot simply reply with "yes". Which did you mean?

If you mean the exponential (the second), then you are done. Use x = 16 and calculate your very large number.
